Re: (no subject)

Hi Allan,

Of course you should keep unnecessary exposure as low as possible, but
don't worry too much. Just don't put your food on the bench (what you
probably would not do, when there are no isotopes around). Probably
there are lots of more dangerous chemicals around which do not
radiate, but nobody cares.

In contrast to 35S, 3H and 14C are not detectable with most standard
monitors, so unnoticed spillage of higher doses is is the real problem
when there is no regular and careful monitoring like swab tests.  I'd
be a bit concerned about 14C as it tends to accumulate in living
beings (what it does anyway from natural sources, that's why your
bones may be dated very well when someone might dig them out again in
a couple of thousand years :). 3H has a short biological half life far
below it's radiochemical t1/2 and 35S decays quite fast.

Have fun!

PS: If you think of shocking your radiosafety advisor (or maybe
yourself), just hold your Geiger counter into your lab's ceramic sink:
Lots of isotopes there (thorium, maybe some radium. Expect the beeper
to go off like a rocket).
